Diagnostic Feature Reference

Orthographic markers used for chronological classification

Period	Feature	Explanation
Archaic	K before /a/	K/C/Q tripartition diagnostic of 7th–5th century scripts
Archaic	No F	F reintroduced after c. 400 BCE; absence suggests earlier date
Classical	C dominant	After c. 500 BCE, C replaces K and Q as general velar stop
Classical	Aspirates (θ, φ, χ)	Aspirated consonants become more consistent in Classical orthography
Late	F present	F from Latin /f/ appears in late Etruscan as labiodental fricative marker
